APPARATUS FOR TREATING HIDE? Specification of Letters Patent.

Patented Apr. 4, 1922.

Application filed November 27, 1920. Serial No. 426,765.

To (all whom it may concern:

Be it known that I, EDWARD J. ALLHISER,

a citizen of the United States, and a resident of Philadelphia, in the county 7 of Philadelphia and the State of Pennsylvania, have invented certain new and useful Improvements in an Apparatus for Treating Hides, of which the following is a specification.

This invention relates to a device for applying to the outer faces of hides a liquid solution, usually a sulphide, preparatory to dehairing. -The object of the invention is the economical application of the solution, avoiding unnecessary waste and also avoiding the applying of the solution to the inner side of the hide, which application not only results in a loss of a certain amount of the solution but is injurious to the hides so treated.

A further object of the invention is a device of this character in which two hides are placed face to face, bringing their inner sides together, and are then subjected to a spray of the desired solution, a portion being sprayed from above on the uppermost hide and a portion from below on the outer or hairy face of the lower hide.

The invention also consists in the novel features of constructionv hereinafter described, pointed out in the claim and shown in the accompanying drawings, in which Figure 1 is an end elevation. .liigure 2 is a top plan view. Figure 3 is a section on the line 33 of Fig. 2, a pair of hides being shown in place and a roller bearing being shown partly in section.

The apparatus employed by me comprises a vat 1 adapted to contain the liquid with which the hides are to be treated. Over one side of this vat and forming a partial. cover for it is placed a table 2, inclining downwardly toward the central longitudinal line of the vat. A second and lower table 3, inclined in the same direction, is placed over the opposite side of the vat, with its lower edge spaced from the vat side so that any, liquid running down the table 3 will drain back into the vat.

on an extended shaft portion of the upper roller, as at 7. V

A pump 8 ofv any desired type is placed at one end of the vat and is connected to the bottom of the vat by a supply'pipe 9. Liquid is pumped from the vat into upper and lower feed pipes 10 and 11, perforated as at 13 along their opposing faces, so that they spray the outer hairy facesof the hides as they pass between them. It'will be understood that the hides are placed with their inner faces together and fed through the rollers and betweenthe pipes 10 and 11, being introduced at the upper side and removed from table 3. The liquid drippingfrom the hides runs down the table and drains back into the vat, and is again pumped through the pipes and resprayed, so that there is no waste of liquid. While I have described and shown the device as treating two hides at a time it will be understood that the vat and rollers may be of such length that more than one pair of hides can be run through at one time.

I do not desire to be limited to any particular form of pump or vat, as these can be altered without making any change in the invention.

What I claim is A hide treating apparatus comprising a vat, two tables arranged above the vat spaced apart and inclining in the same general direction, feed rollers arranged between the tables, spray pipes arranged one above the other and perforated! to discharge a liquid toward each other, and a pump adapted to draw liquid from said vat and discharge it through said pipes, one of said tables draining back into the vat.

In testimony whereof I afiix my signature.

EDWARD J. ALLHISER.
